ANTICORRODSIVE COMPOSITION.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed Aug-ust 15,- 1906. Serial No. 330.753-

. plication to metal and serving when applied to protect the material. against corrosion from any source. 3

In producing the composition of the present invention I use copperas, gum-asphaltum, ivory-black, drier, varnish, (preferably a good oil varnish, such .as used by painters for outside Work,) linseed-oil, turpentine,

litharge, glue, sulfate of zinc, gum-shellac, and dark gum-amber. As a result of a mixture of these ingredients a aint-like composition is produced, which is designed to be applied directly to the articles to be protected in a manner similar to the application of aint.

n the preferred proportions and manner of forming the composition the ingredients are used in the following manner; Twentyfour ounces of gum-asphaltum in pulverized condition is melted in a suitable receptacle, to which is slowly added in succession eight ounces of linseed-oil, twenty-four onces of finely-ground ivory-black, one ounce of litharge, one ounce of sulfate of zinc, and two ounces of copperas. The mixture is al lowed to boil for about three -hours and the dark gum-amber added, about two ounces of the latter being used. The mixture is further boiled for about two hours and allowed to partially cool, whereupon one ounceof the guru-shellac and thirty-two ounces ofthe varnish are added during continuous agitation of the mass. One 'ounce of glue is then added and the mixture heated for about thirty minutes. After cooling drier and turpentine in the proportions of about twenty-four ounces of the dryer and eight ounces of the turpentine are added to reduce the consistencv of the mass to permit its proper application.

The composition made up in the manner and approximately in the proportion stated is to be applied to any metallic surface andwill be found to have rendered said surface non-corrosive as well as antifouling and acidproof. T he mixture is applied in the manner'usual in the application of paint, being of a consistency permitting such application in a ready and convenient manner.

. The composition is primarily designed for exposed metallic surfaces, being particularly effective with machinery of all character, I

roof structures, metal fences, and the like.

' While preferring to make up the composition in the manner and in the proportions above stated, it is to be understood that I do not specificallv limit myself thereto, as slight variations willnot seriouslyinterfere with the efficiency of the composition and are to be considered within the scope of the present invention. This is particularly true of the specific ingredients named, as the chemical equivalents thereof, if such exist, will prove equally effective.

Having thus described the invention, what is claimed as new is 1. An anticorrosive composition comprising copperas, gum-asphaltum, ivory-black, litharge, sulfate of zinc, a binding agent, and a liquid vehicle.

2. An anticorrosive composition comprising pulverized gum-asphaltum, linseed-oil, ground ivory-black, litharge. sulfate of zinc, copperas, dark gum-amber, gum-shellac, varnish, glue, drier, and turpentine.

3. An antic'orrosive composition comprismg pulverized gum-asphaltum twenty-four ounces, linseed-oil eight ounces, ground ivorynate len th of time, adding theneto dark: gum-am er, subjecting themiXtui-eto further boiling and a partial cooling, adding In testimony whereofi I: afix' signature in presence of two witnesses.
